Alright. To me it feels like you’re going at it backwards. The way to learn things / to program / Meteor is to have a desire to build something, to have a desire for something to exist, and then to go about imagining and moving towards it and eventually accomplishing it – and finding that through the process you have learned what you intended to learn and more.
Why the localmarket app? What is it that you would like to build with what you imagine you would glean from a tutorial that walks you through building the localmarket app? And then how about just setting out to build that and ask specific questions along the way?
(I don’t want to dismiss the value of a tutorial, and having lots of tutorials available for everything under the (Meteor) sun. But they can only go so far in real-world teaching. The fun and learning really only begins once you start building something you need or someone else needs and you have a desire to provide them with.)
So, yes, ask for specific help and I and others will be glad to give pointers and answers. And it’s great if you’re already full at it, building what you desire to build, and your statements just made it seem to me like you weren’t already!
